问题描述
我的laravel应用程序中有几个页面,我需要在Facebook中共享链接.
I have several pages in my laravel app that I need to share link in Facebook.
事情是,当我共享它时,Facebook从登录页面获取了og:image属性,因为它是由我的中间件重定向的.
Thing is, when I share it, Facebook get the properties og:image from login page, as it is redirect by my middleware.
我在此处看到必须检测Facebook用户代理和重定向到仅具有openGraph属性以在Facebook中呈现链接的公共页面.
I saw here that I must detect Facebook User Agent and redirect to a public page that should only have the openGraph properties to render link in Facebook.
这是唯一的方法吗?
我最终将创建一个内部软件,其中带有一个开关,用于管理我拥有的所有公共公开页面,这不是很好...
I will end up creating a middleware, with a switch inside, to manage all the differents publics pages I have, it is not so nice...
任何想法我该怎么做?
推荐答案
我通过创建自己的中间件解决了它:RedirectCrawlers
I solved it creating my own Middleware : RedirectCrawlers
<?php
namespace App\Http\Middleware;
use App\Tournament;
use Closure;
use Illuminate\Support\Facades\Route;
class RedirectCrawlers
{
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
$crawlers = [
'facebookexternalhit/1.1',
'facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)',
'Facebot',
'Twitterbot',
];
$userAgent = $request->header('User-Agent');
if (str_contains($userAgent, $crawlers)) {
switch (Route::getCurrentRoute()->getPath()) {
case "tournaments/{tournament}/register":
$tournament = Tournament::where('slug', $request->tournament)->first();
return view('public/register', compact('tournament'));
}
}
return $next($request);
}
}
然后我创建了一个resources/views/public/register.blade.php
Then I created a resources/views/public/register.blade.php
<meta property="og:title" content="{{trans('core.competitors_register') }}"/>
<meta name="description" content="Registrate en el torneo {{ $tournament->name }}"/>
<meta property="og:description" content="Registrate en el torneo {{ $tournament->name }}"/>
<meta property="og:type" content="website"/>
<meta property="og:image" content="https://kendozone.com/wp-content/uploads/2016/04/home.jpg"/>
<meta property="og:image:secure_url" content="https://kendozone.com/wp-content/uploads/2016/04/home.jpg"/>
<meta property="og:url" content="{{$request->url()}}"/>
<meta property="fb:app_id" content="780774498699579"/>
<meta name=" twitter:title" content="{{trans('core.competitors_register')}}"/>
<meta name="twitter:image" content="https://kendozone.com/wp-content/uploads/2016/04/home.jpg"/>
<meta name="twitter:card" content="summary"/>
<meta name="twitter:description" content="Registrate en el torneo {{ $tournament->name }}"/>
这是一个公共页面,仅具有共享到Facebook所需的信息.
that is a public page, that just have info needed to share to Facebook.
然后在App \ Http \ Kernel.php中,在验证中间件之前,将路由添加到"web"中的$ middlewareGroups内,以便将其重定向到公共页面:
Then in App\Http\Kernel.php I add the route inside $middlewareGroups in 'web', before Authenticate Middleware, so that it redirect it to the public page :
\App\Http\Middleware\RedirectCrawlers::class,
解决方案存在于stackOverflow中,如所评论的那样,但对于Laravel 5.3而言,都不存在!
Solution exists in stackOverflow, like commented, but none of them for Laravel 5.3!
希望有帮助!
